Abstract

The aims of this research were to produce a higher embryonic growth and a higher hatching weight, as well as to find out the most effective time for amino acids injection into incubated eggs. The study was carried out in a factorial (4 x 2) arrangement according to completely randomized block design. The first factor was different levels of amino acid injections i.e. A0 = (control), A1 = injection of lysine at a dose of 3.78 mg/0,5 mL of sterile distilled water, A2 = injection of methionine at a dose of 1,91 mg / 0,5 mL of sterile distilled water, A3 = injection of lysine + methionine at dose of 3,78 lysine+ 1,91 mg methionine/0,5 mL of sterile distilled water. The second factor was different injection time, namely T1 = injection on day 7 of incubation and T2 = injection on day 14 of incubation. Total number of treatment combination was 8. The incubation of eggs was run three times in wich each period served as a blok/replication for each treatment combination. Therefore total number of eggs used for the entire experiment was 900. Parameters measured were yolk weight, albumen weight, embryo weight and hatching weight. no acid that the amino acid injection into eggs significantly affected (P <0,05) the weight of the embryo and hatching weight. The timing of amino acid injection significantly affected (P <0,05) the weight of the yolk but the interaction between amino acids and time of injection had no significant effects (P> 0,05) on all parameters. We conclude that amino acid injection (in ovo feeding) with lysine, methionine, or combination of lysine and methionine can increase the weight of the embryo and hatching and the moust effective time to inject amino acid on day 14 of incubation.
